Just for the purpose of isolation, try to download other application that has a webcam application like yahoo messenger or skype. If it still does not work, most probably there might be a loose connection or simply the webcam itself is defective. You might need to contact Dell to have it serviced.
On the other hand if yahoo messenger or skype works, you can either just used these applications or try to reinstall the software (dell webcam manager).

This is happening because the Dell webcam central is accessing the webcam at the same time as yahoo messenger. Click on start and click on Run(XP), Type MSCONFIG in start search (Vista) and you'll get the system configuration utility. Open it and go to the startup tab. Uncheck anything related to Dell webcam. Click on Apply and OK and restart the computer. If yahoo messenger shows a black screen uninstall Yahoo messenger and reinstall with the more recent version.

Download Yahoo Messenger (www.yahoo.com) . Create a free ID on yahoo as ask the other person to do the same. Install Yahoo Messenger and Login using your ID and start IM conversation. You will get a webcam button on the IM (instant Messenger) window . Click on that and the other person will see you and vice versa. This is just one way, there are other messengers too and gmail too offers video conversation in its mail. So enjoy
